Abstract
A considerable number of onsite material test programs have been conducted at different geothermal sites to provide a database which permits characterization of materials used, or considered potentially useful, for geothermal turbine applications. These programs have included the exposure of test specimens of different materials to geothermal steam from a steam resources, as at the Geysers, or in flashed steam from a hydrothermal source, such as at Baca, New Mexico (1) and Cerro Prieto, Mexico (2). The results of an onsite test program performed at the Geysers for more that three years, are presented. Some aspects of geothermal turbine design which take into account materials behavior in geothermal steam are also discussed.
